Why do you sleep worse during warm nights?

During sleep, your body temperature naturally drops. This is a natural process that helps you enter deep sleep. When your bedroom is too warm, your body has to work harder to cool down. As a result, you fall asleep less quickly and wake up more often during the night.

You also perspire more. When heat and moisture are not properly dissipated by your bedding, a stuffy feeling arises, making you sleep less comfortably.

Precisely for this reason, not only the room temperature plays a role, but also the material you sleep in.

What is the ideal bedroom temperature?

For most people, the ideal bedroom temperature is between 16 and 18 degrees Celsius. During a heatwave, this is naturally difficult to achieve, but every degree of difference helps. The goal does not always have to be to make the room freezing cold. It's mainly about preventing heat from building up and creating a comfortable sleeping environment.

With the tips below, you can easily achieve that.

1. Keep the heat out during the day

Many people open their windows as soon as the sun starts to shine in the morning. However, this often backfires.

When it's warmer outside than inside, warm air flows in. This gradually heats up walls, floors, and furniture. This stored heat is then radiated for hours, even after the sun has set.

Therefore, during the day, keep:

• windows closed;

• curtains or blackout blinds closed;

• awnings or roller shutters down as much as possible.

Especially south-facing bedrooms can remain several degrees cooler this way.

2. Ventilate as soon as the outdoor temperature drops

As soon as it cools down outside, it's important to let in fresh air.

Open windows opposite each other to create a natural airflow. Do you have multiple floors? Then you can also open a window upstairs and downstairs to dissipate warm air more quickly.

A fan can help by improving air circulation.

The faster warm air leaves the bedroom, the better you will sleep later that evening.

3. Choose breathable bedding

Many people think that a fan or an open window makes the biggest difference. In reality, your bedding also determines how hot you feel at night.

Synthetic fabrics retain heat and moisture for a relatively long time. This makes your bed feel clammy and makes it harder to cool down.

Bedding made of 100% Egyptian cotton works differently. Thanks to the extra-long cotton fibers, a strong, soft, and breathable fabric is created that absorbs moisture better and wicks it away faster. This keeps the sleeping climate more pleasant, even when the temperature rises.

4. Use a summer duvet

A common mistake is that people still sleep under the same duvet in July and August as in winter. As a result, body heat remains trapped around the body.

A summer duvet with a lower TOG rating or a light cotton sheet often feels much more pleasant during warm nights. Combine this with a breathable duvet cover made of 100% Egyptian cotton for optimal sleeping comfort.

5. Avoid heat sources in the bedroom

Electronic devices produce more heat than many people realize.

For example, think of:

• televisions;

• laptops;

• computers;

• gaming consoles;

• chargers.

Do not leave these devices on unnecessarily and unplug chargers when not in use. Traditional lighting also emits heat. LED lighting is therefore a better choice during warm summers.

6. Take a lukewarm shower

After a hot day, an ice-cold shower sounds wonderful. However, your body reacts by producing extra heat to get back to temperature. A lukewarm shower works better. Your body gradually cools down, making it easier to relax and fall asleep faster.

7. Use a fan smartly

A fan does not cool the air, but ensures that warm air continues to circulate. This allows sweat to evaporate faster and makes your body feel cooler. A handy trick is to place a bottle of frozen water or a bowl of ice in front of the fan. The air flowing past the ice feels just a little fresher.

It is better not to direct the fan directly at your face all night. This can cause dry eyes or a stiff neck.

8. Choose light colors in the bedroom

Light colors create a fresh look and absorb less heat than dark colors. Although the temperature difference is limited, many people experience a light bedroom as calmer and cooler.

White, sand-colored or light blue duvet covers also fit perfectly with a summery bedroom.

9. Wash your bedding more often during warm weather

During warm nights, you lose more moisture through perspiration. This moisture is absorbed into your sheets and pillowcases, making the bed feel less fresh. By washing your bedding weekly during a heatwave – and possibly changing your pillowcase mid-week, your bed remains comfortable and hygienic.

Not every material feels the same during warm weather. Below you can see the main differences.

Sometimes small habits seem harmless, but they make a big difference.

Common mistakes include:

• leaving windows open during the day;

• sleeping under a winter duvet;

• choosing synthetic bedding;

• leaving electronic devices on;

• starting to ventilate late in the evening.

By avoiding these mistakes, you can quickly create a more pleasant sleeping environment.
